Each year of data is based on taxable years ending within the calendar year unless otherwise noted.
Although you requested 2021 data, the data for all taxable years that end within the 2021 calendar year is not complete and therefore is not provided in this letter. For example, taxable years ending December 31, 2021, are not due until May 1, 2022, and if the return is extended, are not due until November 1, 2022. As a result, complete data for 2021 is not yet available.
